There are two types of acoustic guitar namely the steel-string acoustic guitar and the classical guitar. Steel-string acoustic guitars produce a metallic sound that is a distinctive component of a wide range of popular genres. Steel-string acoustic guitars are sometimes referred to as flat tops. The word top refers to the face or front of the guitar which is called the table. Classical guitars have a wider neck than steel-string guitars and are strung with nylon strings. They are primarily associated with the playing of the solo classical guitar repertoire. Classical guitars are sometimes referred to as Spanish guitars in recognition of their country of origin.
